m_iWndWidth = GetSystemMetrics(SM_CXSCREEN); // Supposed to get window width, but gets COMPUTER MONITOR WIDTH!
m_iWndHeight = GetSystemMetrics(SM_CYSCREEN); // Same thing
MoveWindow(hChildWnd, 0, 0, m_iWndWidth, m_iWndHeight, FALSE); // This would be a situation with only 1 child window (for testing)
Child window auto-resize?
Author
I'm currently in the midst of developing a Map Editor for a 2D RPG in c++. I just finished writing the engine yesterday (or so I think), and I have a seemingly trivial problem but it's not. When I create my main window, I also create 2 child windows in the main one. The main window is 800 x 600, and the child windows fit perfectly TO THE PIXEL thanks to the GetSystemMetrics function. But when I resize the main window (i.e. maximize), the child windows obviously stay the same size. I need help with a technique to auto-resize the child windows when the main one is resized. Here's what I tried, but it didn't work.
can anyone help me?
According to the msdn documentation, SM_CXSCREEN gets "The width of the screen of the primary display monitor, in pixels. This is the same value obtained by calling GetDeviceCaps as follows: GetDeviceCaps( hdcPrimaryMonitor, HORZRES)."

Wow don't I feel dumb. :) Thanks njpaul. I guess I was searching for the wrong thing. This should definitely do it.
You could try SetWindowPos(...) or setting the FALSE to TRUE for the redraw.
I'm doing Win32 stuff at the moment. I'll remember to mess around with this myself and see if I can learn anything.
EDIT: ah, solved before I could post and more correct than mine :(
